Someone sent me some nep seeds as Christmas present last year. Sown the pack on 6th Jan 08 following instructions articles published onthis forum. Day by day the seeds got darker and now they are black. Black = dead?
Please advise.

Could you give us more details like the media you use, humidity, light, etc.?

Yup.. a picture could tell a thousand words too  |

Chopped S.moss in a "Sime Fresh lettuce" box with 2 quarter inch hole on top. About an inch of the moss then seeds on top. Mist every 2-3 days. Left by the balcony window, with direct morning sun and indirect in the afternoon. Weekend I just open the box to air the stuff (whenever I am around or remember).

They could be rotted.

bactrus, our natural tropical weather is good enough to help seeds germination. There is no need to cover the box. The warmth and extreme humidity will encourage fungus attack.

Yes agree with Robert...
I lost a few species of seeds due to the same mistake...
But i have a question... if we try germinating neps seeds in life sphagnums moss will it also get fungus attack?

The idea that so many "experts" give regarding seed germination has little useful information, yet these myths are what people "believe" as gospel. The truth underlying seed germination has broken these myths and dispelled misconceptions about seed germination on soil.
The successful idea is to grow them "outside" of a flask environment. Do not create a test tube life when they are equally able to germinate and grow in a natural environment. The truth of the matter is that invitro cultivation leads to rapid mortality rates of seedlings. Not the other way around, as lead to believe by these so-called "experts!"
As more and more people actually abandon the false hearsay regarding seed germination, the quicker and better we actually do start to improve on our cultural techniques and therefore grow better plants. I have seen so many "see the light," so to speak and from a "once upon a struggling time..." to now growing the so called highland, specialists and rare plants with ease.

I have some experience in tissue culture palms. These test tube babies are indeed more fragile compared to seedlings. Special care needed. However when it comes to germination rate, those in 'controlled' enviroment fare much better than those in the 'wild'. But when it comes transplanting... it is the other way round.
Tissue culture plants, given enough care (additional) will definately keep extinction of species in check. Protocol for CPs I think will be more refined hence maybe once rare CITES controlled species may be available for mass commercial sale.
Will try the open method as recommended by Robert. How about Drosera seeds. The Intermedia I bought from Pisces seeded. Using similar method as Neps. Incidentally, are thsoe seeds fertilised? Just flower from a plant.
Appreciate your advise(s).

Thanks Robert for the advice...
Actually is tissue culture plant such bad? because i know of many grower who are happy with these plant and they have no different with seeds grown plant... or is there? (at lease those that i have are the same)
Cultivating and growing cp's are actually a fun and enjoy thing's to do... i just wish everyone could be happy while seeing their seeds germinating and seeing the plant they love grow while pitchering...

The problem with tc is that we rely too heavily on ARTIFICIALLY propagated material. While having SOME tc plants available is a way to have species available at any given time (exceptions: N. hamata, edwardsiana, jacquelineae, izumiae, clipeata, northiana, macrophylla, etc. ) we should always have some seed originals for a species survival mechanism.
There are also problems with some tc that have been propagated and repropagated without replacing the mother stock plant. While some aberrations may deem desirable (variegations, multiple side branching, etc.), others are not (premature flowering, infertile pollen, abortive seed capsules, dwarfism, webbing, fusion, aborted immature pitcher development, poor rooting, stemming, inability for a plant to pass the juvenile stage, intolerance to outside conditions, inability to ward off diseases, poor resistance to natural conditions, etc.).
While some aspects of tc may deem valuable, until a plant that can be truly tc'd from one known clone to make exact replicas, the current seed embryo method yields no guarantee to form, clone or type.

Yes, tissue culture is prone to abnormalities; some only obvious years later. By then, the question of to cull or not is difficult to answer. All tc successes and failures depends on protocols. Like orchirds tc has been very successful. I strongly support tc especially when it comes to those critically endangered species. Maybe Siti can answer this.
Also, yesterday while checking the N mirabillis tray, saw some green stuff that looks like germinated seeds. Observing them, hopefully not weeds. Better not count chicken before they hatch.

There has been too much talk (literature and other forums) which make claims that seed growing is difficult and that tc is faster, easier, better. Let it be known that the opposite is fact and that again the status quo is false.
I have seen so many beginners grow seedlings to maturity with astounding results not because they are super horticulturalists, but rather they have employed good growing practices, employ fertilization techniques and know when to do things based on plant appearances.
It will not be long before the many of us will have not only a growlist but also a hybrid list to boast. As making hybrids, germinating seeds and growing-trading new plants with others.
